Executive summary

Rocket Lab Q1 FY26 — Record Revenue, Backlog, and Strategic Acquisitions Drive Growth

Rocket Lab delivered a record-breaking Q1 FY26, driven by strong demand across its launch and space systems segments, highlighted by significant contract wins and strategic acquisitions. The company is aggressively advancing its Neutron development and vertical integration strategy, aiming to provide end-to-end space services. While investments in growth initiatives continue to impact free cash flow, Rocket Lab maintains a robust liquidity position to fund future expansion.

Highlights

5
  • Record revenue of $200.3 million, up 63.5% year-over-year.

  • Record GAAP gross margin of 38.2% and non-GAAP gross margin of 43%.

  • Record total backlog of $2.2 billion, up 108% year-over-year, including largest-ever Neutron contract.

  • Secured access to over $2 billion in total liquidity, positioning for growth and M&A.

  • Booked 31 Electron and HASTE missions and 5 Neutron contracts in Q1, exceeding last year's total bookings.

Concerns

3
  • GAAP operating expenses were $132.5 million, above guidance, primarily due to a stock-based compensation charge related to Peter Beck's RSU forfeiture.

  • Non-GAAP free cash flow was a use of $77.4 million, remaining elevated due to Neutron development and scaling production.

  • Q2 FY26 GAAP gross margin guidance of 33%-35% and non-GAAP gross margin guidance of 38%-40% reflect a shift in Space Systems mix towards lower-margin SDA programs.

Deals & partnerships

Motiv Space Systems acquisition

Definitive agreement to acquire Californian-based leader in space robotics, motion control systems, and spacecraft mechanisms. Motiv's technology is on CADRE Lunar Rover and NASA Mars Perseverance Rover (robotic arm, zoom/focus/filter wheels).

Mynaric acquisition

Acquisition closed, adding optical communication terminals and a European presence. Aims to capture demand in the accelerating European space and defense market.

Anduril partnership

Teaming up for 3 dedicated HASTE launches to support missions for the Department of War. First launch scheduled no earlier than November this year.

Raytheon partnership

Rocket Lab and Raytheon selected to demonstrate advanced capabilities for the Space-Based Interceptor program under Golden Dome, strengthening national missile defense.

Capital programs

Neutron Development Program underway

Ongoing investment driving elevated capital expenditures and negative free cash flow. Includes testing, production scaling, and infrastructure expansion.

Return on Investment (Landing Barge) underway

Benefit:enables Neutron reusability

Massive barge, over 11 million pounds, with 10 megawatts across 4 station keeping thrusters. Housing for thrusters and main cabin installed. Power generation systems and thrusters arrived at shipyard.

Electron Factory Expansion underway

Benefit:52 Electron launches per year

Factory designed for 52 Electron launches per year. Modest capital investments needed to reach full capacity. Two pads at Alpha 1 and a third pad at Wallops are already available.

Risks & headwinds

Stock-based compensation charge Q1 FY26

$11.4 million increase in GAAP SG&A, $132.5 million GAAP operating expenses (above guidance)

Elevated Non-GAAP Free Cash Flow Consumption Q2 FY26 and beyond

-$77.4 million (Q1 FY26)

Mitigation:Ongoing investments in Neutron development, scaling production, and long-lead procurement for SDA programs are necessary for future growth.

Gross Margin Impact from Space Systems Mix Shift Q2 FY26

Q2 FY26 GAAP gross margin guidance 33%-35% (down from 38.2%), Non-GAAP gross margin guidance 38%-40% (down from 43%)

Mitigation:SDA Tranche 2 and 3 programs bring significant scale. Management expects overall margins to expand as Electron cadence increases and new acquisitions mature.

Neutron Development Program Risk Until first flight and beyond

Unquantified, but inherent in development programs

Mitigation:Careful commitments, extensive parallel testing campaigns, and re-evaluation of reusability plans based on Flight 1 reentry results.

Initial Margin Drag from Mynaric Acquisition Initial quarters post-acquisition

Unquantified, but described as 'a bit of a drag on margins'

Mitigation:Management is confident in improving the business to achieve target margins through integration and optimization.

Q&A highlights

What key items should investors track for Neutron's first launch, and what is the customer feedback on Neutron bookings ahead of its debut?

Investors should track the placing of large vehicle components on test stands. Customer feedback is strong, with aggressive customers booking early due to trust in Rocket Lab, despite not offering discounts.

“the more aggressive customers are making sure that they don't miss out their opportunities to fly early.”

Detailed narrative

End-to-End Space Company Strategy

Rocket Lab emphasizes its unique position as an end-to-end space company, leveraging vertical integration across launch, spacecraft, and subsystems. This strategy allows control over quality, schedule, and cost, enabling the company to provide comprehensive solutions from responsive small satellite launches to constellation deployments and national security missions.

The goal is to eventually deploy and operate its own space-based applications and services, representing the largest addressable market.

National Security Focus and Partnerships

The company is deeply integrated into national security programs, supporting SDA's Proliferated Warfighter Space Infrastructure, the DoW's Mach-TB hypersonic program, and the Golden Dome Space-based Interceptor program. Strategic partnerships, such as with Anduril for HASTE launches, highlight its role in advancing defense capabilities with commercial speed and tactical responsiveness.

Rocket Lab and Raytheon have been selected for the Space-Based Interceptor program, demonstrating advanced capabilities for national missile defense.

Vertical Integration and Subsystem Expansion

Rocket Lab continues to expand its technology stack through both organic development and strategic acquisitions. The acquisition of Motiv Space Systems brings in-house critical spacecraft mechanisms like robotic arms and drive assemblies, reducing reliance on external suppliers. The organic development of the GA electric propulsion thruster further enhances its vertical integration, aiming to break bottlenecks in the electric propulsion market with high-volume production and serve both internal and merchant markets.

European Market Expansion

The acquisition of Mynaric not only adds optical communication terminals but also establishes Rocket Lab's first European footprint. This expansion positions the company to capture growing demand in the European space and defense market, estimated at up to $109 billion by 2030, by offering a wide range of capabilities from optical comms to responsive launch and high-volume subsystems.

This strategic move opens new programs, partnerships, and revenue streams.

Neutron Development Progress

Significant strides have been made in Neutron's development, including design refinements for the Stage 1 tank, progress on automated production of components, and successful stage separation tests. The 'return on investment' landing barge is also progressing, with housing for thrusters and main cabin installed, aiming for sea trials later this year.

Extensive testing of Archimedes engines and qualification of other flight components are underway, all timed for the first launch later this year.

Space Systems Mix Shift and Margin Dynamics

The Space Systems segment's growth is increasingly driven by large SDA contracts (Tranche 2 and 3), which, while providing significant scale and absolute dollar contribution, come with a lower gross margin profile. This mix shift is impacting overall gross margins in the near term, but management expects margins to expand in launch as cadence increases and believes the Space Systems division can achieve target margins long-term through efficiency gains and integration of new acquisitions like Mynaric.
